I'm trying to use pip to install various requirements in my virtualenv, but I can't get around the error Segementation fault (core dumped). That error seems to indicate memory access problems, but I don't understand how or why that would happen in a venv.

  • Are you sure you are running the pip that you intend to run? try to issue the command: which pip. – Eddie Dunn Mar 08 '19 at 18:15
  • It looks like it's running pip from the venv: `(soverton) soverton@osr-ubuntu-2:~/Documents/eroi-erp$ which pip /home/soverton/.local/share/virtualenvs/soverton-mUoZmsRb/bin/pip` – Shaun Overton Mar 08 '19 at 18:24
  • Also, I confirmed that user soverton has read-write permissions on that folder – Shaun Overton Mar 08 '19 at 18:36

I solved this by first creating an environment using Python 3.6: pipenv --python 3.6. In this environment, both pip and pip3 worked. I then exited this environment, deleted both Pipfile and Pipfile.lock and then created another environment using pipenv --python 3.7.2 in the same directory and both pip and pip3 worked again.

I guess it must be an issue with Python 3.7.2?

Edit:

As Shaun mentioned below, it could be to do with anaconda being installed alongside vanilla Python and removing anaconda fixed it.

first find out the location of pip.

run which pip

The output will points to a file. just rename the file with extension .py That's it
